7FC Double Inverted Magnetron Cleanable Cold Cathode Sensor Part Number: 2-2146-052 Description Operating Range Analog Output Supply Voltage Mounting Orientation Calibration Medium Overpressure Analog Output Resolution Operating Temperature Storage Temperature Bakeout Temperature Response Time Accuracy 1 x 10 to 1 x 10 Torr Controller-dependent Controller-dependent Any Dry air or nitrogen 150 PSI Controller-dependent 0° to +50° C -20° to +70° C 200° C < 10 ms The 7FC cold cathode sensor has a measurement range from 1 x 10-11 up to 1 x 10-2 Torr. It indirectly measures absolute pressure by ionizing gas in the presence of a magnetic field. Unlike hot filament sensors, the 7FC is resistant to inrushes of gas. The design of this sensor allows for easy disassembly enabling quick cleaning and extended use. The 7FC can be operated by the Televac MM200 or MC300 rack mountable controllers. These controllers automatically operate the cold cathode to provide a full range vacuum measurement solution when the 7FC is used in conjunction with rough vacuum sensors.
